AVFs may be considered the best type of venous access for chronic hemodialysis in pediatric patients with more than 20 kg who are not likely to receive a kidney transplant or be transitioned to peritoneal dialysis within one yr. The aim of the study was to report the experience in the creation of AVFs in pediatric candidates for renal transplantation using microsurgical vascular techniques, with emphasis on the details of the surgical technique. Forty children underwent 50 fistula creations - 31 radial-cephalic, 11 brachial-cephalic, five brachial-basilic and three saphenous-femoral. The vein was anastomosed to the artery in an end-to-lateral fashion by using two separate 8/0 prolene running sutures. The overall patency rate was 76.0%:22 (70.9%) of the radial-cephalic fistulas, nine (81.8%) of the brachial-cephalic, five (100.0%) of the brachial-basilic and two (66.6%) of the saphenous-femoral. There was no significant difference in patency rates between the brachial-cephalic, brachial-basilic and radial-cephalic fistulas. The incidences of fistula patency were not different for patients weighing <20 kg compared with patients weighing >20 kg. AVF remains as a satisfactory method for providing hemodialysis in children. The utilization of microsurgical techniques with some technical refinements described herein permits the achievement of high fistula patency rates.
对于体重超过20公斤、不太可能接受肾移植或在一年内转为腹膜透析的儿科患者,动静脉内瘘(AVF)可被视为慢性血液透析的最佳静脉通路类型。本研究的目的是报告使用显微外科血管技术为儿科肾移植候选者创建AVF的经验,重点是手术技术细节。40名儿童接受了50次造瘘手术——31例桡动脉-头静脉内瘘、11例肱动脉-头静脉内瘘、5例肱动脉-贵要静脉内瘘和3例大隐静脉-股静脉内瘘。采用两根单独的8-0聚丙烯连续缝线以端侧方式将静脉与动脉吻合。总体通畅率为76.0%:桡动脉-头静脉内瘘22例(70.9%)、肱动脉-头静脉内瘘9例(81.8%)、肱动脉-贵要静脉内瘘5例(100.0%)、大隐静脉-股静脉内瘘2例(66.6%)。肱动脉-头静脉内瘘、肱动脉-贵要静脉内瘘和桡动脉-头静脉内瘘的通畅率无显著差异。体重<20公斤的患者与体重>20公斤的患者相比,内瘘通畅发生率无差异。AVF仍然是为儿童提供血液透析的一种令人满意的方法。采用本文所述的一些技术改进的显微外科技术能够实现较高的内瘘通畅率。
